Thanks for quickly confirming the fatal error was related to WooCommerce not being active and not the latest version of Store Hours Manager. We will consider the report about the fatal error as closed.
Now regarding new pop-up functionalities and behaviors of the plugin. Yes, in this latest version, the plugin was long overdue for a significant update after the original release 4 years ago to include new free and premium based features and settings. For this release and future development of the plugin, we made major changes to the notification behavior, actions and management mode. Including a change from an Alert Bar to Alert Box using the Free version and new settings for triggers to display the time of the notification by Site or Page using the Free version. We understand these changes are different from the previous version. If you decide the plugin is no longer a good fit based upon these changes, we understand and you can easily revert to a previous version, version 4.1.2 from www.ads-software.com.
For us to continue developing and releasing new freemium and premium features planned on our development roadmap, we needed to make the long overdue development changes. This will also allow us to continue the compatibility support between WordPress and WooCommerce as the frequency of those release occur now. We hope the community can understand and support our efforts to develop and maintain the plugin for the future.
